IMPROVEMENT IN GAS-BURNERS.

Specification forming part of Letters Patent No. 164,528, dated June 15,1875; application filed January 18,1875.

To all whom it may concern:

Be it known that I, ISAAC COOK, of St. Louis, St. Louis county, State ofMissouri, have invented acertain new and useful Improvement inGas-Burners, of which the following is a specification My improvementrelates to a duplex burner and means for obtaining the properinclination of the pillars.

Experiment has demonstrated that the angle of impingement of the jets ofgas, and the distance between the tips to obtain such impin gemcnt,should bear proportion to the pressure of gas in the city where they areused. The pressure of gasin cities varies, and is considerably more thandouble in some to what it is in other cities; therefore the burners haveto be modified to these circumstances. In casting and boring the burnersthey are not all alike as to this distance between the tips, and sorequire nice adjustment in most cases after they are otherwise finished,even where the mold is made to exactly suit one city.

My invention is designed to meet this requirement; and consists inmaking the necks of such burners of thin pliable metal, preferably ofsoft brass. Burners formed in this manner can be readily adjusted by afittingtool, so that a burner for one city can be adjusted to suitanother.

In the drawings, Figure l is a side view of the burner. Fig. 2 is alongitudinal section at a plane passing axially through both branches ofthe burner.

Ais thescrew-socketby which the burner is attached'in the ordinarymanner to a pipe or bracket. This socket has at its upper end two thinbranches, BB, extending in opposite directions. The top of each branchends in a pillar, C, forming the socket of the burner-tip D. The tipsare preferably of the usual bat-win g form, with slits extending transverse1yn am ely, at right angles with the plane of the section shown inFig. 2. The tip and pillar upon one side have such inclination inrelation to those upon the other side that the jetsof gas impingeagainst each other at an angle of about sixty degrees. The jets of gasare first spread into broad flat flames by the slits of the tips, andwill impinge against each other on a line of considerable length, and,by their action 011 each other, are still more expanded and spread outinto a broad thinleaf, in which the oxygenation is very perfect, owingto the extreme thinness and evenness of the flame.

The thin branches or necks B B are made of pliable metal, preferablysoft brass. so that by an ordinary fitting-tool the tips can be bendableaccording to the pressure of gas in the city, so as to obtain thebrightest possible light with each burner.

I claim as my invention As a new article of manufacture, the duplexgas-burner provided with the thin adjustable necks or branches B B, asand for the purpose set forth.
